Abstract: A head mounted display system configured to project a first image to an eye of a user, the head mounted display system includes at least one waveguide comprising a first major surface, a second major surface opposite the first major surface, and a first edge and a second edge between the first major surface and second major surface. The at least one waveguide also includes a first reflector disposed between the first major surface and the second major surface. The head mounted display system also includes at least one light source disposed closer to the first major surface than the second major surface and a spatial light modulator configured to form a second image and disposed closer to the first major surface than the second major surface, wherein the first reflector is configured to reflect light toward the spatial light modulator.

Abstract: An optical system for an augmented reality head mounted display eyepiece that is configured to deliver images to the eye wherein the optical system includes optics. The optics are disposed so as to receive light output from the light source. The optics further arranged with respect to a spatial light modulator such that the light received from the light source passes through the optics and illuminates the spatial light modulator. The light illuminating the spatial light modulator is redirected back through the optics and is coupled into at least one waveguide through at least one in-coupling optical element. At least a portion of the coupled light is ejected from at least one waveguide by at least one out-coupling optical element and directed to the eye of the user.

Abstract: A method for determining a residual retardance of an LCOS (Liquid Crystal on Silicon) panel includes transmitting a light beam to the LCOS panel at an angle of incidence and measuring an intensity of a reflected light beam. The method includes biasing the LCOS panel in a dark state and measuring a dark state intensity of the reflected light beam. The method also includes biasing the LCOS panel in a bright state, and measuring a bright state intensity of the reflected light beam. A residual retardance of the LCOS panel is determined based on a contrast ratio of the bright state intensity and the dark state intensity. The method can also include selecting a compensator for the LCOS panel based on the residual retardance.

Abstract: A computer software system is disclosed for single step coordination between software applications. A monitoring application automatically identifies a target application and presents a prompting window, such that if possible (but not necessarily) it appears to be attached to a side of the target window. Clicking a control in the prompting window automatically activates a secondary application, and automatically transfers information from the target application to the secondary application. Target desktop windows can be identified by their window captions and target HTML windows by their URL addresses. Controls on prompting windows can activate multiple secondary applications and/or different secondary application modes. Information can be obtained from a target application by reading a file stored for that purpose by the target application, by interprocess communication, or by screen scraping.

Abstract: A software system is disclosed having pop-up windows that efficiently deliver informational and/or actionable messages that provide access to medical test results and related information. The otherwise invisible software receives and displays the messages on a computer where a medical professional can immediately access test results and related information. A pop-up window can include controls that delete messages and/or close the window, and can also include codes used to access medical test results, and/or hyperlinks that automatically open separate windows to display medical test results, context information, and/or other related information. Message elements can be arranged in columns and can be sorted by selecting column headers. In preferred embodiments, the medical professional provides identifying information so that only messages directed to the medical professional are displayed, and in some embodiments displayed messages and responding actions are logged.
